Emotions Flashcards
What are the key components of emotion and how do they interact to shape our emotional experiences?
Emotions are distinctive cognition, behaviors, & physiological changes that are a part of evolution.
What is the basis for using polygraph tests to detect lying? What are the limitations and controversies surrounding their use?
It measures the activation of the sympathetic nervous system reflecting stress, not lying.
Controversial because it is applying biomedical science in legal settings.
Based on assumption that people have an emotional reponse when lying. Emotions are usually accompanied by bodily respones
Discuss the evidence supporting the universality of emotional expressions. Are there cultural differences in how emotions are expressed and recognized?
Distinct expressions for anger, sadness, happiness, fear, disgust, contempt, and embarrassment.
Cross-cultural similiaty is noted in the production of specific emotions, yet some groups do not agree on suprise and disgust.
Cultural conditioning enforces prescribed rules for facial expressio
What is the James- Lange Theory of emotion?
Autonomic reaction triggers feelings.
Facial feedback hypothesis: sensory feedback from facial expressions can affect our mood.
People performing task on a certain face report stronger feelings of emotions being simulated.
What is the cannon-bard theory of emotion?
Simultaneous autonomic reaction and feeling
Stimulus— perception/interpretation( danger) —- general autonomic arousal ( heart races) & particulat emotion experienced ( fear)
How does the cannon-bard theory of emotion differ than the James-Lange theory of emotion?
Cannon - Bard claims that emotions happen simultaneously with an autonomic reacion and James Lange says that autonomic reaction triggers feelings
What are the two-factors of Schachter’s theory?
- Emotional labels are attributed to sensations of physiological arousal.
- Which emotions we feel depends on cognitive systems that assess the context of the current situation.
What did the Schachter and Singer experiment show?
Autonomic responses can intensify our emotions, but our cognitive analysis affects which emotion we experience.
How does Schacter’s two factor theory of emotion account for the influence of both physiological arousal and cognitive appraisal on emotional experience?
Emotions provide context to current situations.
What is the role of facial muscles, in meditating facial expressions? What are the two categories?
Facial muscles are innervated by two cranial nerves: the facial nerve VII and the motor branch of the trigeminal nerve.
1. Superficial facial muscles- Attache between points of facial skin.
2. Deep facial muscles - Attac to bone; produce larger movements like chewing.
Less facial muscles cases people to experience emotions less intensely.
What are the two cranial nerves that mediate facial expressions?
Facial muscles are innervated by the facial nerve VII & the motor branch of the trigeminal nerve ( V.)
What the role of the CNS pathway when emulating emotions?
The face you emulate affects your emotions.
What is the facial feedback hypothesis?
The facial feedback hypothesis suports the James-Lange theory.Sensory feedback from our facial expressions can affect our mood.
How does electrical brain stimulation provide insights into the neural circuits in the brain?
It can produce emotional effects. Brain-self stimulation: animals will work to receive electrical stimulation to their brain. Most self-stimulation brain sites are subcortical and concentrated in the medial forebrain bundle.
